Ryanair will tomorrow unveil a significant expansion of its services from Dublin Airport.

It's expected that executives will detail plans for additional winter services as the airline cranks up pressure on IAG-owned Aer Lingus.

Transport and Tourism Minister Paschal Donohoe will be at the Ryanair event in Dublin, which is also being attended by the carrier's chief marketing officer Kenny Jacobs, and chief commercial officer David O'Brien.

Last week, Ryanair chief executive Michael O'Leary confirmed that he expected the "mother and father" of fare wars this winter across Europe.

Ryanair is expected to base more aircraft than previously expected at Dublin Airport this winter.
